LEVER CATCH.

Application mea Marchal, ieee. semi Np. 629,647.

To all 'whom t may concern:

Be it known that I, FRANK H. MACE, a citizen of the United States, residing at Medina, in the county of Orleans and State of New York, have invented new and useful Improvements in Lever Catches, of which the following is a specification.

The object of my said invention is the provision of a simple, conveniently operated andl safe lever catch adapted when the lever is moved in one direction to automatically catch and hold the lever against retrograde movement, and also adapted when the lever is further moved in the same direction to automatically release the lever and permit the same to move in reverse direction back to its original position.

My novel catch is designed more particularly, though not necessarily, for use in association with the clutchl pedal lever of an automobile.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanyingV drawings, forming part of this specification:-

Figure 1 is a side elevation showing the clutch pedal or foot lever as it appears prior to being moved forwardly to any extent.

Figure 2 is a horizontal section taken through the lever in the plane 2-2 of Figure 1 above the catch.

Figure 3 is a view showing the lever engaged with the catch after the first forward movement of the lever.

Figure 4 is a similar view illustrative of the manner in which following further forward movement of the lever and the release thereof, the lever moves back to its original position.

Figure 5 is a detail elevation illustrating the opposite side of the lever to that shown in Figure 1.

Figure 6 is a detail showing how the lever moves back to the position of Figure 1 without being engaged by the catch.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The levez` 1 is subject to retraction by an appropriate spring 2, and is hingedly connected and supported at its lower end as indicated by 3.V

Appropriately supported in proper relation to the lever 1 is a standard 4 to which is fixed an arm 5 havingat 6, Figure-5, a-

stop. The lever 1 is provided with a lateral pin 7, and a gravitational catch 8 is pivoted at 9 to the arm 5 and is arranged in parallelism with the'line of movementof the lever l.

Figure 5 shows clearly that in the preferred embodiment of my invention one end of the catch 8 is bifurcated as indicated by 10 to receive thestop 6, and to enable the lower arm of the bifurcation to bring up against the stop 6 with a view to limiting the downward movement of the'beveled end 11 of the catch 8. In addition to the beveled end 11 the catch 8 vis provided with an inclined notch 12. and a stop 13.

lfivotally connected at 14 to the catch 8 is a gravitational guard 15, which is normally pendent on the catch 8 as illustrated in Figure 1.

In the practical operation of my'improvement it will be readily understood that when the lever 1 is moved a short distance toward the left in Figure 1, the pin 7 will raise the catch 8, and the said pin 7 will be seated in the notch 12 of the catch with the result that the lever 1 will be safely held against retrograde movement.v It will also 4be manifest that on further movement of the lever 1 toward the left the pin 7 will raise and pass the guard l5, whereupon the lever will be moved backward by the spring 2 and will ride under and raise the guard 15, the said guard 15 at that time bringing up against an additional stop 13X on the catch 8. From this it follows that the catch 8 will not interfere in any measure with the return move- `ment of the lever 1 subsequent to the forward movement of the lateral pin 7 beyond and out of engagement with the gravitational guard the future practice of the invention various changes and modifications may be made snch as fall Within the scope of my invention as deined in my appended claim.
